The principle of virtual work sometimes known as the “unit-load” method was developed by John Bernoulli in 1717. It is a direct application of the principle of conservation of energy

Thus, one of the methods of ensuring lateral stability and avoiding excessive lateral deflection is by deploying shear walls across the width of the building to resist the lateral forces.
Flat slabs are reinforced concrete slabs supported directly on columns, without beams. They are sometimes thickened at the columns to form column drops.
Introduction This post concerns the application of lateral loads to barriers and wheel axle loads from vehicles. The nature of this type of loads may…
Introduction Before a column can be designed, the actions to which it must support must be determined. This includes the axial compressive forces and bending…
Introduction Moment redistribution must not be confused with moment distribution, as the two terms are distinctly dissimilar in meaning. Moment distribution is an approximate method…
In this article, we are going to consider how to break down structures into simpler units called a ‘sub-frame’ that can be analyzed discretely.
Introduction With the continuous advancement of computer-based analysis within the field of structural engineering, the tools used for analysis by hand are becoming less relevant.…
Introduction The design of structural elements requires an appraisal of the actions (static and dynamic forces) to which supporting are subjected to, loads transferred from…
